PVP-I for COVID-19
13th treatment shown to reduce risk in February 2021
*, now known with p = 0.000000037 from 20 studies.
Lower risk for mortality, cases, and viral clearance.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
3,800+ studies for 60+ treatments.
Study of the use of PVP-I gargles and nasal drops before and after ENT examinations with a total of 6,692 patients, finding high usability and good tolerance for use.
21 patients (0.76%) reported an itching sensation in the nose on the first day of use of 0.5% PVP-I nasal drops and discontinued its further use. However, none of the patients reported any serious side effects or allergic reaction to 0.5% PVP-I nasal drops and gargles.
The 0.5% PVP-I gargles and nasal drops were used by healthcare workers about three to four times in a day for 5 months. None of them developed any COVID-19 symptoms.
